Help me find manga

Hi, I read this awesome piece and can't find it
It was colored partially
First story was about Mischa who offered bdsm services andone client fell it love with him. I remeber Mischa had previous relationship as a bottom with older guy that died (there was flowergarden?)
Next relationship is friend of Mischa, and it's f1 drivers that fall in love (one is spanish/columbian? the other I dont know). I remember it ended with one of the driver's death in a race
Please help!
